Patented Sept. 1'7, 1907.

Application filed July 25,1906. Serial No. 327,714.

To all whom it'may concern:

Be it known that I, JOHN M. KINAED, a citizen of the United States, residing at Bremond, in the county of Robertson and State of Texas, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to acetylene-gas generators of that type in which the water tank, carbid magazine, gas holder, and so forth, are combined in a single apparatus.

The object of this invention is to provide a new and improved acetylene-gas generator, which is simple and compact in construction and arranged to insure periodic feeding of the carbid according to the consumption of the generated gas. j

The invention consists of certain novel features of construction and combinations of the same in an acetylenegas generator, as hereinafter set forth and claimed.

The accompanying drawing, in which similar figures of reference indicate like parts, illustrate the invention.

Thefacetylene-gas generator is shown in vertical section and in elevation.

1 indicates the water tank, having a flat bottom 2, and containing an internal supplementary bottom 3, secured to the sides of the tank and tapering downwards to an opening 4 in the center, with which is connected a horizontal pipe 5, projecting through the side of the tank and having a cap 6 which screws on to its outer end. The pipe 5 is connected with a vertical pipe 7 by means of a T-joint 8 which is adapted to turn on the pipe 5. The upper end of pipe 7 which terminates about at the top of the tank 1 is provided with a screw kcap 9. Access is had to the tank 1 by means of an opening 10 at its side closed by a cover plate 11, held against a gasket 12, and therlange projection 13 about the opening 10 by means of suitable bolts 14 forming a gas-tight joint. The tank 1 may be filled by removing the cap 9 from pipe 7 and supplying water through the same, the relation of the pipe 7 to the tank 1 being such, that the tank 1 will be; filled only to the top of same, any surplus of water overflowing at the top of pipe 7. By means of the tapering bottom 3, the opening 4 and pipes 5and 7, the bottom of the tank may be readily cleaned out.y By removing the cap 9 of pipe 7 and turning the pipe 7 down on its hinge-joint 8, the sediment or ashes collected at the bottom of the tank will be washed out through pipes 5 and '7 by the pressure of the water. The sediment, etc., in the bottom of the tank may be stirred up prior to washing by removing the covenplate 11 and stirring up the sediment with a proper utensil. Instead of turning down the pipe 7, the `cap 6 may be removed from end of pipe 5 and the discharge made directly from that point.

Surmounting the water tank 1 is a gas-holder 15, having its lower end opening into the top of the water tank 1. The gas-holder 15 may be made as large or as small as desired, according to the required capacity of the generator. Located over the gas-holder 15 is a bell 16, surrounded by a casing 17, between which and the gas-holder 15, water is introduced, which serves as a water seal for preventing the escape of gas from the holder, the b ell projecting down into said water seal.

Mounted on the top of the casing 17 are a number of vertical projections 18, each carrying a roller 19, there being in this instance four of these roller bearings, against which the bell 16 impinges and moves up and down. By means of these projections and rollers the bell is prevented from toppling over in case it is run high up by the charge of carbid and gas generated therefrom.

The carbid magazine, which consists of a vertical casing or cylinder 20, having a pipe 21, communicating with an opening 22 at its lower end, is mounted on top of the water tank 1 as shown. The top of the casing 20 is closed by a cover-plate 23 which is secured at the top of the casing 20 by bolts 24, a gasket 25 being inserted between the plate 23 and the edge of the casing 20, thereby forming an air tight joint. `The cover 23 may be removed by unscrewing the bolts 24, when access to the magazine is required. Carbid is supplied to the casing 20 through an opening 26 in its top, closed by a screw cap 27. The opening 22 in the bottom of the casing 2O is closed by a valve 28 formed of two cones secured together, giving it pointed ends. The upper end of the valve 28 is connected by a rod 29 with a weight 30, inclosed in a small casing 3l, mounted in brackets 32 in the casing 20. The valve 28 is normally held down against the opening 22 by the weight 30, the rod 29 moving through a hole in the bottom of the casing 31. The casing 31 protects the weight 30 from being interfered with by carbid inserted in the casing 2().`l The lower end of the valve 28 is connected by a rod 33 extending through the pipe 21 with a lever 34, pivoted to a bracket 35 in the water tank l, the other end of the lever 34 being pivotally connected to the lower end of a rod 36 extending up through the gas-holder 15 and a few inches above its top. The rod 36 extends through an opening 37 in a cross-piece 38 mounted on the sides of the gas-holder 15 and holding the rod 36 in an upright position.

The relation of the top of the bell 16 to the rod 36 is such, that when the valve 28 is closed the gas in the holder 15 and above it supports the bell 16 above and away from the upper end of the rod 36. When the gas is drawn off and decreases in quantity the bell 16 descends and its top coming against the upper end of the rod 36 pushes the latter down and thereby acts on lever 34 and rod. 33to open the-valve 28 to permit more cari.-V

bid to pass down pipe 2l into the Water tank l. The Y gas .again generating in the gas-holder raises the belland its top moving up away from the upper end of rod 36, Weight 30 pushes down the valve and closes it and,

through the lever mechanism, causes therod 36'toxbe` pushed up. The double pointed ends and shape of the valve 28 is such, that as it is movedup, and down in the carbid it Will act to stir up and agitate the same and cause it to feed down through the pipe 2l into the Water tank l.

lights and which may be closed l'bya cock 43, if itis desired to shut off the supply of gas. The lower-end of pipe 42 projects into a small receptacle or chamber 44, Whichserves to catch'all settlings, or other extraneous matter droppingfrompipe 42'and accumulating from the gas, thereby preventing such accumulation from being carried up into the pipe 42 and stopping invention, What I 1.'
